>> Somebody added one on my Philco 37-60B. Doesn't show up on the schematic. Afraid to try it out.
Use a modern DMM, measure the AC voltage relative to the GND (chassis) on both input sockets.
Then measure DC. If the DC is significant, put 1MOhm resistor across and re-measure. If it is small (should be on an order of a volt or lower), you do not have to be afraid of using it.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
